IMPROVEMENT IN TELEGRAPH-INSULATORS.

Specification formirg part of Letters Patent No. 149,763, dated April14, 1874; application filed December 31, 1873.

UASE A.

To all whom it may concern:

Be it known that I, CHARLES L. Ln BARON, of Pensacola, in the county ofEscambia and State of Florida, have invented a new and ImprovedBracket-Insulator for Telegraph Wires; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing bad to the accompa- .nying drawing forming a part of thisspecification, in which Figure 1 represents the insulator attached to apost and supporting the line-wire, in perspective. Fi 2 is a top view ofthe device.

The invention relates to an insulator having two slots arranged at rightangles to each other, one being open to receive the line-wire, the otherclosed to adapt the bracket to be The former is deeper than the other,so that the wire may be placed in the insulator before it is hung on thespike, as hereinafter described.

To this end I construct the device A of any suitable non-conductin gmaterial-as glass or wood-and give it, preferably, a rectangular form.To adapt it for attachment to the pole or post by a spike, B, I provideit with a vertical slot, 0. The spike has its outer end bent upward tohold the insulatorin place; but, as

an additional means of seeurin g it, I generally employ a tie-wire, I),which is secured around the block just below the spike in shallowgrooves or notches a, as shown. The slot E for holding the 1ine-wire Fis diagonal to the line of direction of the latter, or to the face ofthe block A, except at its lower part, where it is somewhat enlarged.Thus a shoulder is formed at c, which prevents the wire rising in theslot and coming in contact with the spike.

As a further means of securing the parts to gether, a wire, c, maybetied loosely around the line-wire E on each side of the insulator,passing intermediately under the end of the same. Small knobs orprojections '2 are formed on the inner side of the insulator, whichcause the water to drop from it in place of flowing to the post G; andthe operations of putting up or of taking down or splicing the wire areperformed with greatease and dispatch where this insulator is used.

The wire is allowed longitudinal, and also some lateral, movement in theslot E of the insulator; hence neither is so liable to be broken whenthe wire sways or is bein g ti ght ened, &c., as in the case of mostother insulators.

The line-wire is necessarily placed in the slot intended for it beforethe insulator is hung on the spike, and it cannot become detached solong as the insulator remains suspended, whether tie-wires beused ornot. The head or bent-u p end of the spike, while easily passed throughthe vertical slot, also prevents the insulator slipping oft, whether thetie-wires be used or not.

I do not claim an insulator diagonal or spiral slot 5 but \Vhat I claimis- The insulator provided with a slot for the line-wire, formed at aright or nearly right an gle to a slot for a spike, and extending belowthe latter, as and for the purpose specified.
